A setting on a device you already own, not a hidden one
Does your smart speaker actually record you — and who hears it?
Every other page on this site is about finding a device someone hid. This one is about a device sitting in plain sight on your counter, doing exactly what it's supposed to do — and a quality-assurance process most owners never knew existed. Invasive, not malicious: a company improving its speech recognition, not a person spying on you specifically.
What actually happened, company by company
- Amazon (Alexa), reported April 2019. Bloomberg reported thousands of Amazon contractors and staff, working from offices in Boston, India, Romania, and Costa Rica, review Alexa voice clips — about 1,000 per shift per worker — to transcribe and annotate them for accuracy. Amazon confirmed the program existed and said it reviews "an extremely small sample" of recordings, captured after the wake word. Workers told Bloomberg they sometimes heard distressing material, including what sounded like a sexual assault, and said they were told there was nothing they could do about it.
- Google (Assistant), reported July 2019. Belgian broadcaster VRT NWS obtained more than 1,000 leaked Google Assistant clips from a contractor hired to transcribe them. Some contained addresses, details about people's relationships, and what sounded like a person in distress; 153 of the clips had not been triggered by an actual "Hey Google" command — accidental activations, recorded anyway. Google said only about 0.2% of recordings are normally reviewed and opened an investigation into the leak.
- Apple (Siri), reported August 2019. The Guardian reported Apple contractors graded Siri recordings for accuracy, and that workers regularly heard confidential medical information, drug deals, and recordings of couples having sex — much of it from accidental "Hey Siri" triggers rather than real requests. Apple suspended the grading program worldwide within about a week of the report, while it reviewed the process.
What changed afterward
All three companies moved away from reviewing recordings by default. Google made Assistant audio review opt-in worldwide after Germany's data-protection authority ordered it to stop the practice; Apple rebuilt Siri grading as something you opt into, not out of; Amazon added a toggle that excludes your recordings from its human-review and "help improve Alexa" programs. The underlying reason for the review itself hasn't gone away — these systems still improve by having humans check unclear or failed recognitions against what was actually said — but whether your specific recordings go in that pool is now something you control, if you turn the setting off.
Check your own setting (the setting moves — verify the name, not the path)
- Amazon Alexa app: look for a privacy section — the setting has been called "Alexa Privacy," with an option about improving Alexa or Amazon services using your voice recordings. Turning it off stops future recordings from being used that way; it does not erase recordings already made, which you clear separately from the same privacy area.
- Google: look in your Google Account's activity controls for "Voice & Audio Activity" or the Assistant's own activity settings — the control for whether your audio is saved and reviewed lives there, separate from the main on/off switch for the Assistant itself.
- Apple Siri: look under Siri's own settings for a question about sharing audio recordings or improving Siri — this is opt-in by design since 2019, so if you never affirmatively said yes, you're very likely already excluded.
Whatever the exact menu says by the time you read this, you're looking for the same two things: a toggle for whether your voice clips can be used to improve the service (which is what puts a human in the loop), and a separate place to review or delete your recording history. They are usually two different settings, not one.
What this doesn't fix
Turning the setting off limits whether your clips enter a human-review pool going forward. It does not retroactively delete anything already recorded — that's a separate "review activity" or "voice history" screen in the same app — and it does not stop the device from listening for its wake word at all, which is how it works in the first place. If you want the device to stop listening entirely, the only reliable fix is the mute button or unplugging it, not a settings toggle.
Worried about a device you did not set up yourself — a rental, a hotel room? That is the other half of this site.
The field manual covers finding a camera someone deliberately hid. This page covers a setting on a device you knowingly own — different problem, same calm approach.
